6.2 Error-codes
The control panel has an internal diagnostic program to ensure correct functioning of the
Valiant. Three error codes can occur:
1. System error
2. Watchdog error
3. Bus error
If these errors occur, the Valiant should be switched off for at least 10 seconds before
switching it on again. If the code persists, you should contact your dealer.
Appearance of any other error-code is an indication you should also contact your dealer.
